Serial No. 565,322.

This invention relates vto-slidebuckles used for adjustingthe length of looped straps, webbing and the like, without penetrating the material, and, while the invention is adapted 5 to any bent wire Yform of :slide buckle; itis especiallyV adapted to that" class of yslide buckles made" of round vwire bent toform a pair of loops connected at one side and free -at the opposite-sides'andrhaving intermediate bar-structure portions integrally extending from the free sidesV of the loops to the connected side thereof. Y The objects of the invention are to provide a reversible slide buckle having strapgrip ing bar-structures iiattened in the plane o the buckle and also bar-structures having spaced projections extending out of the said plane; to provide a slide buckle of the pair of loops type of which the upper and lower bar-structures are flattened in the plane of the loops, and the intermediate bar-struc tures are provided with spacedvprojections extending in opposite directions out of said plane; to provide, means for securing together the free sides of such a pair of loops; and to provide means for securing thefwire ends of the intermediate bar-structure portions to the connected side of the loops. With these and other objects in view as may become apparent from the within disclosures; the invention consists not only ofthe particular form herein pointed ont and illustrated in the draw' ing, but readily admits of certain modifications within the scope of what hereinafter may be claimed.

While the character ofv the invention is broad in its application to the art, reference is here made to one illustrative device embodying the invention and illustrated bv the accompanying drawing in which the Figure 1. is an upright elevation of the device; the Figure 2 is a cross-section on the line 2-2 of the previous figure;

Figure being an upright elevation of a modied form ofthe device.

The device about to prove-ment upon the devices described bv the patents numbered 1,810,647 and 1,672,263 issuedto your petitioner J une 16, 1931, and

f tegrally connected the Figure 3 is al crossV section on the line 3-3 of the Figure 1; the h Y i posite to Vthatof the fnubsr12,

J une .10; 1930, respectively, on slide buckles j ofwliicli both of the intermediate bar-stru@ tures are provided with angular formations proj ectinfr planes perpendicularto, and out of; the plane of Vthe buckle. Referring more particularly to the drawing; however, the slide'l buckle as illustrated is provided with projections formed; not by bending the wire but by press'ng spaced portions of the wire to form nubev projecting therefrom'and the upper and-lower bar-structures are attened in the buckle plane.` 4vThe device is preferably made froma single piece of round -wire of which a middle portion provides the inside bar 1 of a pair of loops 2 and 3 lying in a common plane and formed by bending both Wire end portions in substantial parallel relation to provide the upper and lower horizontal*bar-structures 4 and 5 of the pair of loops 2 and 3; both wire end portions again bein'gbenn'but inwardly toward' one another, to provide the relatively free sideslG-and 7 of the pair of loops 2 and? 3, and both wire end portions again being bent inwardly and substantially parallel withrthe upper and lower horizontal barstructures i and jto'leave the free sides 6 and 7 in'substantially relative engagement and to provide thel intermediate bar-structure portions 8 and 9separating the pair of.l loops 2y and 3;"tlie intermediate bai'fstructure por tions 8v and QeXtending across the 'buckle and engaging, within the plane of thelloops 2 and 3; with the connecting side bar 1. At some convenient `step in the formation of the slide'buckle, as aforesaid, the spaced nubs 12 are pressed out of the metal of theround wire intermediate bar-structure portion 8 so that the nubs 12 project therefrom out of the saidplane-of thefloops `2 and 3, and the spaced nubs 13 are' pressed out of themetal' of the round wire intermediate bar-structure portion@ so Athat the nubs 13 project tlieref Jfrom out of' the-said plane: in adirection opan-d'the upper and lower horizontal bar-structures ft and be described is im mrl 5 each havingan inner edge portion l14: flat;-l

' tenedin the planeof the Y the loops 2 and'3, the engaging metal Surfaces to provide a rigid structure of the aforesaid form that is reversible in the'sense that the elevation opposite to that illustrated by the Figure 1 is substantially identical to the ele vation asthus illustrated. `While the engaging :metal surfaces of the loops Q'and 3 at 'Y their,l free sides 6 and 7, and the engaging metal surfaces of the extremities: 10 and 11 of theintermediate bar-structure portions 8 and 9 and the connecting side bar 1 arei'llustrated and described as preferably being united in, permanent intimate union, [these engaging parts of the device each inay be relativelyfsecured, if desired, in any less permanent and intimate manner. f

In use, a strap 17 may be threadedv into the slide buckle, as illustrated by the Figure 2, so that the flattened inner edges of the upper and lower bar-structures 4 and 5 and the spaced nubs 12 and 18 extend in different direc-tions into the path of the threaded strap 17 to grip the strap from different angles yto prevent the slide buckle sliding upon a taut strap threaded therethrough.

The modified form of the device, illustrated by the Figure 4f, materially differs from the preferred structure only in that the nubs 12 and 13 are provided by an intermediate bar-structure portion 8 and the upper andV lower horizontal bar-structure 4 and 5 are flattened substantially throughout, not only their entire length but their entire width as well, but both modified and preferred forms Y of the device are similar in that they each provide. gripping edges and nubs extending in different directions into the path of a strap threaded into the slide buckle, the modivfied form having engaging metal surfaces, as at 15 and 16 united in permanent intimateunion as in the preferred form. I claim Y Y LA slide buckle structure comprising a piece of wire of uniform'diameter throughout its length and bent to forni a substantially rectangular frame having side, upper,`

in opposite directions-and cooperating with the inner edges of the flattened bar-structures to' grip a strap `threaded intothe slide buckle.

2. A slide buckle comprising a piece of Wire of uniform diameter throughout its length and bent to form a pair of loops in a common plane, the loops being integrally connected at one side and free, but engaging one with the other, at the opposite sides, intermediate bar-structure portions integrally extending from the free sides to engage their extremities with the connected side, the upper and lower `bar-structures being flattened in the plane of the frame and the intermediate barstructure portions being provided with spaced nubs, eachnub being pressed out of said'uniform diameter to extendbeyond :the portions of the' intermediate bar-structure offwhich portions a full diameter is maintained between, and at the rear ofsaidnubs, saidnubs i i extending out. of'said plane in opposite directions and cooperating with the inner edges of the flattened `lbar-structures to grip a strap threaded intothe slide buckle, means unit,

ing in permanent intimate union the engagv ing metalsurfaces of the` free sides of theH loops, and means likewise uniting the engaging metal surfaces vof the extremities with the metal surface of the integrally-connected side of the loops.

V.Toi-inn noMKnn f ico lower and intermediate bar-structures, the Y `upper and lower bar-structures being fiattened in the plane of the frame and the -intermediate bar-structure being provided with spaced nubs, each nub being pressed out' from said uniform diameter to extend beyond the bar-structureV of .which a full diameter is maintained' between, and at the rear of said a nubs,rsaid nubs extending out of said plane
